Tonton Streaming Combat! (1962) S1E2 - Rear Echelon Commandos

On the frontline, the squad receives three new replacements straight from rear echelon duty in England. They are Gainsborough (a scared, overweight cook), Temple (an equally scared ex-ballet dancer), and Crown (a radio announcer whose cocky attitude masks his fear). Saunders reluctantly takes these newcomers on a dangerous recon mission and discovers that his survival depends on the ingenuity of these misfits.
